There were quite few examples that I am sure would have excited the knowledgeable. I think its an annual event - some attendees were comparing today's excellent weather with previous years more "challenging" systems😈

I agree with your logic but unfortunately not with its application. Fuel flow data is from two Red Cubes (fuel flow sensors). One on the main delivery line between mechanical pump & carburettors and one on the return to tank line. The return line Cube data is subtracted from the main line Cubes data to give fuel used/fuel remain information to the pilot. There is also a fuel flow readout, that helps in engine power setting. Fuel pressure is registered by a sensor, located at the end of dedicated line, coming of the fuel distributor. The distributer, takes fuel from the pump, delivers fuel to each carburettor, the tank return and the deadened (no flow) pressure sensor line. The return line has a fixed restrictor jet. As far as I can see there is no opportunity for an increased flow, other than opening the carburettor throttles (higher consumption).😈

Yes! I think they must breed them at Holbrook - to be honest I would not know one from another.😈

Almost certainly false readings - but how & why? Yes its the Dynon Skyview ADAHRS (Air Data/Attitude/Heading Reference System) system that has been playing up. The fuel pressure is part of the EMS (Engine Management System). Mind you both systems are "read"/displayed by the SE SV/D600 screen.😈

Sonex aircraft, Rotax 912 ULS, plumed fairly conventionally. Rotax mechanical diaphragm pump 150 hrs. Facet Boost pump with bypass circuit (includes non return valve) This might test out the brains trust. Usually in Cruise, sometimes on Descent I get a low fuel pressure warning. On occasion, indication as low as 1.5 psi. No change in engine note/performance. Sometimes it corrects itself over a few minutes , other times I switch on the Boost pump for immediate fix. Note: I have already mounted the fuel sensor as high as I can within the engine bay, removed the silicon seal to facilitate changes in atmospheric pressure and drained the fuel pressure line. On the way home from Holbrook, the low fuel pressure warning sounded and pressure dropped to 1.5 psi, well below the Rotax 912 ULS minimum of 2 psi and the usually 4-5 psi. I then noticed, the Fuel Flow had risen from 15 L/hr to 25 L/hr. At this point I switched on my fuel Boost pump - immediate rise to 5 psi AND the Fuel Flow dropped back to 15L/hr - switched off the pump and pressure/flow remained where expected. The same scenario happened again a little later. To me drop in pressure combined with a rise in flow is counterintuitive. This may happen with a garden hose but not a closed fuel system. What might the Brains Trust think is happening.

Sorry I don't follow -When would I have lower voltage? Just back from Holbrook Fly-In - with the exception of an odd random fuel pressure drop, on the way home, Dynon/aircraft worked flawlessly😈

Great day at Holbrook. Fantastic flying weather. The members & Committee have a wonderful set up, everything neat & well maintained. Met a Forum member or two. One with a stunning yellow Sonex. Not a big show but what was there was quality all the way - very nice range of aircraft eg Mooney, Pipistrel Virus SW tail dragger, RV's well represented by a lovely 3 & I think a 7, Some Jabs, 2 Sonex & a Onex, 2 Cirris (one from OzRunways), etc etc😈

Update: With Dynon /Horsham on phone (not all the time) have disconnected/reconnected modules & engine sensors, checked V in all configurations - everything checked out with the correct voltage System going down in same circumstances as before - now just turn off system. Go do something else for a few minutes. Turn back on - all good. So far system has worked flawlessly in the air. Have downloaded Diagnostic Export & sent to Dynon USA. Hope to have something back from the experts next week😈

I have never advocated for ASIC to be "repealed". I would like it adjusted, so as not to be required by private pilots, wishing to access small rural airports , usually infrequently used by RPT aircraft,. Its not just about fuel, its also about access to amenities - bed for the night, food, etc. The fatalistic approach to having ineffective, illogical, legislation imposed on Australian private pilots, achieves absolutely nothing. Instead of passively giving in to this badly applied legislation (as is)- why not write to RAA formally requesting that ASIC modification be placed "on the books" and remain there until archived?.😈

Holbrook this weekend. Weather looks promising. All the signs are for a great fly-in.😈

I apologise if my frustration has been a tad obvious. One BIG POINT this is not "my complaint" it affects all private pilots, particularly those who wish to tour (as I do) in Australia. AND as an infringement, for no good reason, on all our civil liberties - the right not to be burdened/subject to unreasonably restriction is part of our law (constitution ? common law?). The impact of the unreasonable/ineffective ASIC, is on a very small percentage of the population, so will garner little interest from the politicians, media and the public at large. Of the latter, there is a common misconception, that people who fly for fun, are the rich elite, so little sympathy will come from that direction. The only hope is that RAA and similar organisation, will take up the good fight and have this stupid law rescinded.😈

You could go and get checked out in a similar aircraft - do a couple of extra hrs, some circuits/landings/stalls and give RAA another go😈

From limited experince - two aircraft. Unless you are unable or want someone else to do the test flying, you can do it yourself. It sounds like yout pilot has done the initial test - you can now take over (make sure you are listed on the RAA forms as one of the test pilots). RAA provide a detailed test schedule (download from website) that you can work through. My first test aircraft was one that I did a complete internal/external refurbishment on over 12 months. Unaware of the potential for disaster, I went ahead and did all the necessary flying to prove airworthiness and conformity with type performance (turned out to be a little better). Second & current aircraft - I purchased a well advanced plans built Sonex Legacy project. As the completer (took another 18 months) I am listed as the builder/manufacturer. I engaged a suitably RAA qualified Inspector, who saw the aircraft once, at near final assembly time. About this time I started looking for a test pilot. I had no idea it would be so difficult to find one. Lots of GA pilots willing to do the job but without an RAA Certificate (bureaucracy!) any test they performed would be invalid. Thinking I may get some help from the Inspector chappy , I contacted him, told him of my difficulty - he did not know of any RAA test pilots in the greater Sydney Basin area. At this, I said if I couldn't find anyone I would do the job myself - he immediately "dumped" me saying I would be stupid to do such a thing and he wanted no part of it. Great help! All's well that ends well - Not only did I find another Inspector, he would be happy to do the initial test flight. Other than issues with engine overheating he conducted the first successful 60 minute test including high speed taxi/hops & several landings and handed the aircraft back to me, with some rigging suggestions and the need to explore better cooling. My Son & I flew off the remaining test hours, adjusted control surfaces for straight & level and spent a long time trying to get engine oil/coolant temperatures under control, eventually succeeding.😈

The only correct answer to a forced landing, is one you survive. You were acting as PIC, made your decision, based on prior knowledge/experince (perhaps not of that beach) & chose what you felt was the best option - hope you got a pat on the back for that one😈

Congratulations. Looks like your green track was having a lot of fun. Dont know much about Jab engines however you may find that your 912 will idle faster in winter. You can live with that or adjust down. I do my winter/summer adjustment at the throttle quadrant (adjusts both carbs at the same time). If you forget to adjust up for summer, you may encounters the occasional engine stop, at or shortly after landing.😈

Coljones, Those of us who are financial members of RAA, have a reasonable expectation, that the organisation will represent the memberships aspirations and concerns, to whatever authority is deemed appropriate. RAA has done this with the aircraft Max weight increase and are in the process of achieving entry to CTA - good stuff for those who wish to take advantage of these changes.. If we expect this sort of representation, what is so hard/unreasonable about taking on ASIC, as it applies to private pilots wishing to access Security Controlled small regional airports? As for individuals approaching their parliamentary representative - "Snowflake's Chance in Hell" of getting any action through this mechanism -I didnt even get a reply to my letter to my member. Ennui reigns supreme 😈

I acknowledge that your can't be bothered approach, is in the majority - thats why nothing will be done! I am sad that neither you or your majority friends, care to even try to correct this wrong. All you have to do is put pressure on our representative body (RAA) to put this matter "in the book" & keep it there, until is satisfactorily resolved.😈

BurnieM, "They can of course then implement the bastard factor and refuse you permission to land and try to 'fine' you if you do." If the PIC declares an emergency, they can land whoever they choose - may be bit of a problem if the emergency found to be bogus. I agree with you - the market will decide what fees are acceptable. Unfortunatly there are owners who will try to extort as high a fee as possible, rather than what's reasonable, for the service provided and the ware/tare of their asset. A fee per ton with minimum charge, is not realy reflective of the ware/tare generated by a 600 kg RAA aircraft.😈

Good man. I try to call all airfields I will pass/one side/overhead within 10 Nm. Yesterday, passing about 8Nm to the north of Goulburn, 5500ft, I had a high performance twin taking off in my general direction. We made pilot to pilot contact. He saw me, I never saw him - all good. Shortly after I passed another aircraft at 4500 ft, several miles to the north - would never had seen him if not for SK2/Ozrunways, he/she made no calls but may have heard me abeam Goulburn/communicating with twin.😈

" ......it's just the system we have." No offence RossK but I am appalled by this statement. None of us should settle for a bad system or part thereof. ".......more traction with the RAAus Board members....." Thanks for that advice. I actually wrote to RAA, assuming that correspondence is readout & discussed at Board Meetings (as per standard Club/Organisation practice). The response I received was from Maxine CEO. I am now wondering if the response is her position or RAA's position😈

I guess the issue(s) come down to: Who controls/owns the air above an airfield? What rights does a PIC have to navigate where /whenever - subject to existing Federal airspace restrictions.? Should it become the "norm" for airfield owners to charge for use of the airspace above - at what point should this charge be levied (height above, distance from, services (if any) provided)? What might be the implications eg avoidance leading to fuel exhaustion/forced landing, would declarde emergencies and emergency response aircraft be fee free ? Landing fees vary, $0-20 (probably more)/landing for an RAA level aircraft - how can this be justified (greed?)? I feel that Australian pilots should remember, almost all airfields were owned by the Federal Government / US!. Due to the adoption of the now discredited Economic Rationalism /User Pays economic model, our short sighted Gov disposed of (sold & gifted) most of the airfields. Much like roads, rail, ports, electrical & water supply that are part of our essential (publicly owned) infrastructure, airfields that were completely open, are now restricted and/or being developed for non aviation purposes. Like most of the other public asset, that have been disposed of, this is an evolving disaster that we the people have allowed to happen (she'll - be right - mate). Public infrastructure/services underpins the economic & social wellbeing of a country, we are the poorer/disadvantaged for the loss of such.😈

I feel for you😈

My faith in humanity is restored - Thanks Jerry_ Atrick. Seems to me that Australians are particularity uninterested in fighting for their rights " she'll - be -right - mate". I am not against having my rights infringed/reduced, where it can be demonstrated that there is a greater good . ASIC not only infringes my rights without a demonstrable benefit BUT also costs me (all of us) as a taxpayer. Australia has the unenviable reputation of being one of the World's' least democratic democracies - ASIC is just a small example of this. It seem that private plots (on this Forum) are quite content with this double rort - if they weren't then their voices would be heard by RAA (our representative body) and something would have to be done, but noooo, all toooo hard. The fact is, no one/or organisation has made a significant effort to get this crap law modified. so that it does not apply to small rural airports.😈

Reference ; Trying to get the need for private pilots to hold an ASIC card , for access to to small rural Security Controlled Airports, abolished I have written to RAA - Got a two nice replies from Maxine (CEO) - in summary, total abdication of their representative function. Advised to contact local member. Have written to local member - as expected no response. If this changes will advise accordingly. The reality is, any politician contacted about this matter, is likly to do the vote maths v risk and decide its not worth their time. 31,000(?) private pilots , spread over the entire country, do no represent a significant lobby UNLESS their representative organisations take up the cause. "'She'll - be - right - mate" (apathy) rules the day😈
